UT4406
Power MOSFET
N-CHANNEL ENHANCEMENT
MODE

DESCRIPTION
The UT4406 can provide excellent RDS(ON), low gate charge
and operation with gate voltages as low as 2.5V by using UTC’s
advanced trench technology which makes an excellent high side
switch for notebook CPU core DC-DC conversion.

SOP-8
FEATURES
